FAN FOR BABY-CARRIAG ES.

SPECIFICATION forming part of Letters Patent No. 575,637, dated January 19, 1897.

Application filed December 31, 1895. Serial No, 573,892. (No model.)

.'Zo @ZZ whom, t may concern.-

Beit known that I, CARL DOLD, a citizen of Germany, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Fans for Baby-Carriages, of which the following is a specication.

My invention relates to fans and devices for operating them; and it consists of an apparatus adapted to be attached to a baby-carriage for operating a rotary fan from the axle of the carriage or by a treadle.

The apparatus is illustrated in the accompanying drawings, in which- Figure l is an elevation of the fan and apparatus, the tubes inclosing the spindles being shown in section in order to disclose the shafts and transmission-gearings. Fig. 2 is a section on line 2 2 in Fig. 1. Fig. 3 is a section on line 3 3 in Fig. l. Fig. 4 is a partlysectional elevation of the driving-wheel and clutch. Fig. 5 is a front View thereof. Fig. 6 is a viewthereof from opposite side. Fig. 7 is the same view as Fig. 4, showing wheel and clutch separated. Fig. 8 is a side elevation showing how the fan is attached to a babycarriage and also the arrangement of a-treadle for driving the fan when the carriage is not moved. Fig. 9 is a top view of the truck-beams of a carriage, showing how the driving-shaft of the fan apparatus is mounted thereon in the back of the carriage. Fig. l0 is a side elevation of the same arrangement. Fig. 1l is an enlarged detail showing the modified arrangement of the gearing as used in this case.

Similar letters of reference in the various views indicate corresponding parts.

My improved fanning apparatus is composed of the following parts: Rope-wheelILset on one axle of the carriage-wheels, transmits the motion to wheel L, rotating loosely on shaft F and adapted to clutch with disk M, set on the same shaft. Gears X and X' transmit the rotary motion to the upright shafts I and I', gears Z and Z to horizontal shafts J and J', and gears Y and Y' to the fan-shaft K. rlhus when the carriage is moved the fan is actuated thereby, when the rope-wheel L is clutched with disk M. IV hen the carriage is standing still, the fan may be actuated by a treadle t, operating the shaft F through hook t' and crankf. When the fan is not used, the whole upper apparatus, including upright shaft I, may be slid out from its bearings and removed. This upper rig may be also used for carrying the umbrella inthe manner illustrated in Fig. 10.

In constructing my improved fanning appa ratus I proceed as follows: Shaft F is mounted horizontally across beams E of the carriagetruck in bearings e and e', secured to the beams. Box G, whereinthe leveled gears H and H' are inclosed, transmitting the motion from the horizontal shaft F to the vertical shaft h, is supported on bearing e to beam E of the carriage-truck. Spindle 7L is supported by the pointed set-screw sa, set in the bottom of the box G. Another bearing G is provided in top of box G.

Tube B, inclosing shaft I, is slid over the bearing G on top of the box G. Spindle h extends only through box G and is provided on its end Witha square recess, in which the squared end of the vertical shaft I is fitted. This shaft I is provided with spline 1I, extending its whole length, and hollow shaft I', provided with a key j, fitted into the spline i, slides on the shaft I vertically and revolves with it. These shafts are inclosed in tube B, telescoping with tube B'. Tubes B and Bl are clamped together in adjusted position by clamp-ring b, fastened by thumb-screw b2, drawing together flanges b' of the clamp-ring surrounding tube B, which is split at its upper end. Tubes B and B' are braced against excessive movement by brackets a a', secured to the carriage. The upper end of tube B' is enlarged and forms the bottom of box C, inclosing gears Y Y. This box C forms a also bearings for the shafts I' and J Shaft I' is supported in box C by collar y and is centered therein by set-screwsb. To the shaft I and above the collar y is fastened the bevel gear-wheel Y, driving the similar wheel Y', secured to the horizontal shaft J Tube B3 is flanged on its basis, and this flange is screwed into the side of box C. On this tube B3 slides the tube B2 and is secured thereto in adjusted position by clamp-ring bb, similar in all respects to the above-described clamp. The other end of tube B2 is similarly flanged and screwed into the side of box D, similarly equipped to the box C. Boxes O and D are IOO strongly made and form, together with tubes B B', the., firmly screwed in their sides, an eiicient and adjustable frame, supporting safely the extensible shafts, gearing, fan, and sun-shade.

In tube Brotates hollow shaft J', driven, as described, with the shaft I' by gears Y and Y', and in this shaft again slides the shaft J, be` ing cou pled with it in similar manner as the shaft I is coupled with shaft I'. Shaft K, jourualed in box D and supported by collar in the same manner as shaft I' in box C, is driven by bevel-gear Z Z' from shaft J', cogwheel Z' being secured to the vertical shaft K, centered by set-screw sc, set in lid of the box. In sockets 7o', carried on the lower end of shaft K, fan-blades 7c are secured by screws 7a2. Driving-shaft F may also be made lengthwise adjustable by composing it of two telescopic shafts coupled in a manner similar to shafts I and J. This arrangement is shown in Fig. l., shaft F' sliding in the hollow shaft F and the key f', attached 1o shaft F, engaging in slot f2 in the shaft F'. For ordinary baby-carriages this arrangement would not be necessary; only in such cases where apparatus adaptable to different vehicles be desired.

Shaft F is driven through clutch-disk M by rope-wheel L, when the clutch, normally disconnected, is joined. Clutch-disk M, having slots m in its periphery, is rigidly fastened to the shaft F. Rope-wheel L runs loosely on shaft F and slides thereon. Dog-pin [,adapted to engage in one of the slots m in the periphery of the clutch-disk M, is screwed in the rope-wheel L, whose boss is extended into the grooved collar O. Between it and the bearing e'is slid on shaft F the spiral spring N, which normally keeps rope-wheel L pressed against the clutch-disk M. Fork P, attached to one end Of the rod p, engages the groove in the collar O. This rod p slides in the bearing Q, secured on the truck-beam of the carriage, and is provided with a knob or other suitable handle on the end, projecting from the bearing Q, and with notch q on the side Opposite to fork I). Spring-pin R, passing through a slot in bearing Q, is attached to spring R', secured to the beam E. This pin R is adapted to spring into the notch q when rod j) is pulled in position where fork P disengages rope-wheel L from clutch-disk M. Shaft F may also be driven by a treadle when it is desired to operate the fan without mov ing the carriage. For this purpose crank f is provided in the shaft F. Rod t', hooked to the crank, is connected to bell-crank lever t2, resting on the axle of the carriage, and the otherend of this bell-crank lever is connected by rod t3 to the treadle t, resting on the floor.

Thus by disconnecting the rope-wheel L from the elutch-disk M the fan can be operated by treadle t with a foot when the carriage is not moved.

Fly-wheel S, secured on the shaft F by setscrew s, is to steady the rotary motion of the fanning apparatus and to carry it over all dead-points when shaft F is driven by the treadle.

t1 represents a rod which is also connected with the bell-crank lever t2 and pivotally to the bottom of the carriage, so that the crank F may be turned by rocking the carriage through the same mechanism as is used in connection with the treadle Both thelinks or rods t3 and t (in connection with the treadlc t) may be used simultaneously, or one of the links t3 or t" and its connections may be detached when desired.

The treadle, when not needed, and all the rods connected to it are removed by simply lifting the bell-crank level: Off the axle and unhooking the rod t' from the crank.

It will be found more convenient to arrange the tanning apparatus in the rear of the car riage-truck, as indicated in Fig. IO. The changes in construction and arrangement ol' the parts necessary for this purpose are shown in. Figs. 9 and 1I. Gear-box G is then placed in middle of shaft F, which runs through it, and gear-wheel X, set on the shaft, is kept in position between bearings g g'. Vertical shaft h, carrying beveled wheel X', is supported on its eonically-pointed lower end in a boss set on the bearing g of the box. The tubular frame is supported, as before, by the box G and is braced iu position by bracket a2, screwed on the truck, and by bracket c', screwed on the back of the carriage.

That I claim, and desire to secure by Letters Patent, is*

The combination with a baby-carriage or similar vehicle, of a driving-shaft provided with a pulley designed to be driven by the vehicle-wheels and with a crank adapted to receive a suitable driving-rod, a vertically and horizontally adjustable fan carried by the vehicle and geared to the crank-shaft through intermediate mechanism, and clutch mechanism for throwing the pulley into or out of engagem ent with the shaft, whereby the fan may be actuated by the vehicle-wheels or by other power through a common drivingshaft.

In witness that I claim the improvements described in the foregoing specification I have signed my name in the presence of two subscribing witnesses.
